Add a global option "-T" to xl to enable timestamps in the output from libxl and libxc. This is most useful with long running commands such as "migrate". During 'xl -v.. migrate domU host' a large amount of debug is generated. It is difficult to map each line to the sending and receiving side. Also the time spent for migration is not reported. With 'xl -T migrate domU host' both sides will print timestamps and also the pid of the invoked xl process to make it more obvious which side produced a given log line. Note: depending on the command, xl itself also produces other output which does not go through libxentoollog. As a result such output will not have timestamps prepended. This change adds also the missing "-t" flag to "xl help" output.
